Abstract

Traitement de ciments. Après avoir préalablement fractionné, si nécessaire, le ciment devenu inactif à des grosseurs de grains inférieures à 7 à 10 mm, on le soumet en l'espace de 0,01 à 0,001 seconde à 3 à 8 chocs par grain dans un désintégrateur, c'est-à-dire un moulin à couronnes ou chenilles portant des battoirs disposés par rangées circulaires, concentriques et à diamètre croissant sur deux disques parallèles entraînés en sens opposé Réactivation de ciment devenu inactif.Treatment of cements. After having previously fractionated, if necessary, the cement which has become inactive to grain sizes less than 7 to 10 mm, it is subjected in the space of 0.01 to 0.001 seconds to 3 to 8 shocks per grain in a disintegrator, c 'That is to say a mill with crowns or caterpillars carrying beaters arranged in circular rows, concentric and with increasing diameter on two parallel disks driven in opposite direction Reactivation of cement become inactive.
